Analysis of Multicarrier CDMA System with Adaptive Subcarrier and Power Allocation

Open publisher page 4 citations

Abstract

Multicarrier code-division multiple-access (MC-CDMA) is one of the effective techniques to gain its multiple access capability, robustness against fading, and to mitigate the ISI. The paper proposes a dynamic subchannel and power allocation algorithm for MC-CDMA system. In the proposed scheme, data is transmitted over the user's best subcarrier and power control is applied for the selected subcarrier, rather than transmitted over all the subcarriers. Analysis and simulation results show that the proposed scheme outperforms the conventional MC-CDMA in BER performance.
